Considering I align cars quite often, you'd be surprized of how much toe you'll gain by dropping a car on it's bumpstops. In most cases when guys drop their car 2"+, you'll see a total of 1/4 or more in toe change...that's HUGE. Sure it may track somewhat straight, but they are all usually darty (combined with horrible tie rod angle) and unpredictable. Trust me, once you ride in a car with good roll correction and tie rod angle, you'll know the difference.
Remember, even as little as an 1/8" will cause more scrub wear than -3* of camber...that's from my personal experience, as well as common knowledge across the board. Camber wears the tire obviously at an angle, but at an even rate...toe however will rub an edge off in no time flat, especially in an instance where there is already significant wear on the tire.
For the 100th time, does he need these things? No. Will it kill tires quickly if you don't fix the problem? Yes.
For the cost of the ISIS or Circuit sports kits, and the coilovers, it is just common sense/practice to get them and set it properly.
FWIW: Just got done aligning a car literally this evening. Front toe (never been changed this side of coilvoers) was a full 1/4 total.
